title: Preparation and evaluation of collagen I/ gellan gum/β-TCP microspheres as bone graft substitute materials.
abstract: Collagen I is the main component of protein in bone and exhibits many excellent applications in biomedical fields. Gellan gum possesses good biocompatible, biodegradable and good mechanical property, and shows great potentials as tissue engineering scaffold or cell culture substrate. Therefore, the aim of this study was to use collagen I, gellan gum and β-TCP to prepare collagen I/gellan gum/β-TCP microspheres by emulsion method as bone graft substitute materials. The preliminary results showed that collagen I/gellan gum/β-TCP microspheres had particle size distribution between 500-1000 µP in diameter and exhibited better mechanical strength. These microspheres also showed good biocompatibility in cell activity test.
